INSEAD bills itself as as "the Business School for the World" and a close look at the nationalities of the MBA students in the school's Class of 2020 gives ample evidence to its claim. The top three nationalities? India, with 15.1%, China, with 10.4%, and the U.S., with 8.8%. Those three counties alone account for more than one in three INSEAD students. When it comes to who uses INSEAD's MBA to switch countries two nationalities stand out: The Lebanese and the Indians. Only 4% of the Lebanese in the program return to their country for post-MBA employment; just 16% of the Indian students return home for a job.
